Now that Time Inc. has turned over documents to federal court, presumably revealing who its reporter, Matt Cooper, identified as his source in the Valerie Plame/CIA case, speculation runs rampant on the name of that source, and what might happen to him or her. Tonight, on the syndicated McLaughlin Group political talk show, Lawrence O'Donnell, senior MSNBC political analyst, claimed to know that name--and it is, according to him, top White House mastermind Karl Rove.

I'd be willing to bet that if it is Rove, he's smart enough to insulate the papers with names of underlings or lower positioned officials. I'm sure nothing gets out of the White House without Rove's permission, but it would be a huge lack of judgement on his part if he can be connected (primarily) to the papers.
